Hy!
I have a RC oscillator circuit with two integrators and one inverter. I do not understand how in the output can be sinus signal, when the circuit input has a DC signal. Why that circuit begins generate a sinus signal? What is here different than the Wien`i bridge RC generator?
The other question is understanding with that line:
Differentiating a square wave results in narrow pulses coinciding with the input transitions when the RC time constant is much smaller than the input pulse width.
English is not my mother-tongue so I have a little problem to understand with that line.
